树干注药技术的基本原理与应用

Basic principles and applications of trunk injection technique

树干注药技术具有施用精准、药物利用率高、接触风险低和环境污染少等优点。当喷洒和灌根施药等手段难以发挥作用或对环境造成污染时,树干注药是更为合适的手段,其开发和应用已引起国内外广泛关注。概述树干注药技术的树木生理学原理和影响树干注药的因素,系统介绍国内外无压力注射、打孔压力注射和微孔压力注射的技术设备和特点,以及树干注药技术在防治松材线虫病等病虫害中的应用,旨在为树干注药技术的发展和优化提供参考。

Trunk injection technique has the advantages of accurate application,high utilization efficiency,low contact risk and less environmental pollution.When spraying and root irrigation of chemicals are difficult to play a role or cause pollution to environment,trunk injection is a more suitable method,and its development and application have attracted wide attention at home and abroad.The tree physiological principles of trunk injection technique and factors affecting trunk injection were summarized,the equipments and characteristics of non‑pressure injection,pressure injection with drilling and micro‑pressure injection both domestically and internationally were systematically introduced.Furthermore,the application of trunk injection in the prevention and control of diseases and pests such as pine wilt disease was also introduced,aiming to provide a reference for the development and optimization of trunk injection technique.
